The awesome Rivet Clamp thread reminded me - we need a fresh tool C-130 in 1/72, from A to J and beyond. You could have a dozen models, each a different version in a different paint scheme flown by different operators.
General aviation planes in 1/32 sounds reasonable, as I feel 1/48 is a little small. Revell Germany makes gliders in 1/32, so why not?
